No biographical details are currently known.
I have found a couple of undocumented appearances by Antonio, so there are probably more.

- Curro Jiménez (1977 TV series) S. 2, Ep. 7: "Entierro en la serranía", IMDb. I have checked this episode, but I was unable to recognise Antonio and the credits were cut. Maybe someone else will have better luck?
- Esa noche (2005 short film) IMDb says "Antonio Peral" is credited, but his one-off appearance in a short film 28 years after his last role would seem highly unlikely.
Titles where Antonio is listed as appearing somewhere online, but cannot be found. There always has to be one!
- All'ombra di una colt (1965) IMDb as Blacksmith. The actor playing the blacksmith is not Peral, maybe confused with I due violenti where he does play this role.
- Finger on the Trigger (1965) IMDb as Tom Sharpe. There is a "Jose Peral" credited, but Antonio does not appear and there is no "Tom Sharpe" character - agreed by Carlos.
